Carbonized Fiber AIFLON 2100 Carbonized Fiber Packing Braided from shrink-proof oxdized polyacrylonitrile fiber impregnated with PTFE dispersion containing graphite particles,silicon-oil-free,Compared to traditional carbon fiber packing,it is not brittle,can suited for high peripheral speeds.It has high strength and good thermal conductivity.PTFE and graphite mades the packing have excellent self-lubrication,so thes packing does not damage shafts and has long life. AIFLON2100I Carbonized Fiber Packing Reinforced with Nickel wire The wire reinforcement provides incerased mechanical strength,usually for static. Application:Used in weak acds and alkalis or media containing few grains of solid particles,both dynamic and static,mainly used for centrifugal pumps,plunger pumps,mixers and valves.
